Episode 03, The Lens

E03 The Lens Show notes:

Note: This episode contains some erroneous information about Ilford Direct Positive Paper. Graham states that it is no longer in production. This information is not correct.  Direct Positive Paper is still in production after a short interruption. For more information on this, listen to the Sunny 16 Podcast episodes 100a, 100b, 100c where they visit the Harmon Technologies Ilford headquarters. 

Nick and Graham talk about lenses and how they can impact a camera build. They talk about why the lens is the most important part of any camera build (5:40) and why it might be a good idea to blend a Debonair lens and a Leica body.

Graham explains why focusing a lens is overrated (18:28) and why you should tape the focusing mechanism of your camera in one position to try out working with a fixed-focus hyperfocal setup. Nick then suggests that the humble mousetrap could provide good functionality to a homemade camera (33:15).

They talk about different methods of attaching lenses to camera bodies including screwing the lenses right to the body and the use of retaining rings for large format lenses (34:10).

The Garbage Cam Challenge has reached its due date and the boys are not as successful in this as they would want to be (53:22). Graham describes his camera made from the discarded paperboard from a 12 pack of soda, a pinhole made from a beer can (56:11) and wooden dowels (INSERT SIZE) that fit tightly in the 135 cartridge reels.

Episode 01, The FrankenBessa

The second episode (after Episode 00, The Manifesto), Nick and Graham discuss Graham’s creation the FrankenBessa, a camera made from the body of a Voigtlander Bessa 6X9 120 camera and a lens designed for 4X5 cameras.

Graham refers to the K-Pan 6X14cm camera designed by Paul Kohlhaussen as an inspiration for the project. As the FrankenBessa project moved forward, it returned closely to that original inspiration (though in a smaller format) as the final project uses the same hyperfocal setup as the K-Pan.

Later on, Nick introduces the Garbage Cam Challenge wherein each participant creates a camera (pinhole or lensed) from junk laying about the house and uses it for various upcoming photographic assignments. No part of the camera can use a part that was designed for use in a camera with the exception of 35mm film canisters for film transport.
